Lua: Autoincrement audio send channels of selected tracks

[swiiscompos]

Here is a script that auto-increments the audio sends for a selected track. It found it extremely handy when I created my orchestral template. It's a hack of js_Autoincrement audio send channels of selected tracks

Notice: track audio outputs and sends must already exist before the script is launched.

--[[
 * ReaScript Name:  Autoincrement audio send channels of selected tracks
 * Description:  Autoincrements the audio send channels of selected tracks.
 *               Particularly useful when routing an instrument track to already existing  
 *               (for example when creating orchestral templates)
 *               The audio outputs must exist before the script is launched
 *               The sends must already exist
 *               The script starts with a dialog box in which the user can select the following:
 *                  - The starting channel from which to increment.
 *                  - Whether to remove MIDI sends from the selected tracks, which makes the routing matrix easier to read.
 *               This script is a modified version of juliansader's js_Autoincrement midi send channels of selected tracks
 *

          reaper.SetTrackSendInfo_Value(selTrack, 0, sendIndex, "I_SRCCHAN", sendIndex*2)
          
          -- Remove MIDI sends (I_MIDIFLAGS : -1 for none)
          if removeAudio == "y" or removeAudio == "Y" then
              reaper.SetTrackSendInfo_Value(selTrack, 0, sendIndex, "I_MIDIFLAGS", -1)
          end

     if chan == 64 then chan = 1 else chan = chan + 1 end
